For details, refer to the VxVM documentation.
5. Remove any sd or ssd disk to be managed by HDLM from VxVM control.
For details on how to remove any such sd or ssd device from VxVM control, refer
to the VxVM documentation. If HDLM has been installed, remove any such sd or
ssd device from VxVM control as directed in 3.13.3 Removing Devices from
VxVM.
(9) Set Up SDS and SVM
When SDS or SVM uses the sd or ssd device to be managed by HDLM, clear the
device settings. For details, refer to the SDS or SVM documentation.
If you plan to use a SDS or SVM shared diskset, make sure that the hardware
configurations of all the hosts are identical (host type; HBA type, number, slots; the
number of paths and the HUBs and switches through which each path passes; and the
storage ports and LUN used by each LU).
(10) Set Up Sun Cluster
If you are using Sun Cluster, before installing HDLM, perform the following
operations to release the device group and Quorum device settings.
• Release the disk device groups that consist of the sd or ssd devices to be managed
by HDLM.
For details on how to unregister an SDS or SVM diskset, see (5) Remove SDS
Settings or (6) Remove SVM Settings in 3.17.2 Preparations for HDLM
Uninstallation. Unregistration of a diskset deletes the data in the diskset.
Therefore, back up a diskset before unregistering it.

following procedures:
1.
Place the target disk device group offline.
# /usr/cluster/bin/scswitch -F -D
disk-device-group-name
2. Start the
